Description

Technical Field

[0001] The present application relates to the technical field of water conservancy and hydropower pipeline installation, and more specifically, to a fastening structure used in water conservancy and hydropower construction. Background Art

[0002] In the construction and installation of urban municipal water conservancy and hydropower pipelines in hydropower tunnels, when the two sections of pipelines are butt-jointed and fixed, they can be fixed and limited by bolts through flanges, and when the middle joint and the two sections of pipelines are positioned and connected, it is usually necessary to manually lift the pipeline port to unify the axis lines of the middle joint and the two sections of pipelines, and then the bolts between the flanges can be smoothly installed. The existing public technology number CN220688233U proposes a water conservancy and hydropower construction fastening device. The device, through the setting of a protective mechanism, first inserts the card block into the inner wall of the card slot during the protection of the pipeline of the water conservancy and hydropower construction, so as to limit the first protective pad, and then screws the first screw clockwise into the first threaded hole and the second threaded hole to fix the first protective pad. At this time, the water conservancy and hydropower construction The construction pipeline is placed above the first protective pad, and then the motor is started. The motor drives the ball screw to rotate through the rotating shaft. At the same time, the rotating ball screw drives the ball nut, the second fastening plate and the second protective pad to fall downward until the second protective pad fastens the water conservancy and hydropower construction pipeline, so that the first protective pad and the second protective pad completely wrap the water conservancy and hydropower construction pipeline, thereby effectively protecting the pipeline. With respect to the above-mentioned related technologies, the utility model inventor believes that the following defects still exist: the fixing mechanism in the comparative literature cannot realize the axial centerline positioning of the middle joint and the two sections of the pipeline when the two sections of the pipeline are butt-jointed and installed. It is usually necessary to adjust the position of the fixing mechanism multiple times or manually lift the pipeline port, and the installation efficiency is low. In view of this, we propose a fastening structure for water conservancy and hydropower construction. Utility Model Content
